Honestly, I don't. It is just that there's no way to take it off in my profile as per Facebook standard. As to Facebook, beginning the user updates its wall to Timeline, there is no way to change it. The visibility could only be changed from your computer, on your browser, on your phone but in the Facebook wall, it won't.
I recently knew from a co-blogger that there is a chance to take it off. Her husband did the magic. And one co-blogger told a link on how to but did not checked it yet. Hopefully by the knowledgeable hands of individual (not from Facebook, because that isn't there concern, as their policy is "as is") I can changed my standard wall. :-(
Any idea how?
